My UMC died last night. It has been plugged in to the wall outlet in my garage since August 2013. Last night when I plugged it in it worked for 10 minutes or so, then I got a message that charging was interrupted. Unplug and replug did no good. I plugged in my new car's UMC and charged up fine. Recommendations? A new one is $650 so a $200 repair bill would certainly be acceptable. But I don't know where to take it. Two and a half year life is pretty poor quality in my opinion. I'm a little disappointed and not looking forward to replacing these things every 2-3 years. Hopefully I just got a bad one.
